Three brand-new Nexus 4 accessories are appearing on the US Play Store (UK, Canada, and Germany too) today: a wall charger, a microUSB cable, and a set of earbuds with a built-in microphone. The wall adapter is a rather steep $16, the microUSB cable $10, and the earbuds $20.

Basically, you're probably vastly overpaying for all of this stuff, should you so choose to invest in it - 2.1A wall adapters (with two outlets, no less) can be found on Amazon for $10, and microUSB cables for a few bucks at Monoprice.
